The United States is committing billions of dollars toward development in Central America and Mexico as part of a plan to strengthen economies in the region and curb illegal immigration, the U.S. and Mexican governments said on Tuesday.

“Finally, we see that Mexico and the U.S. are on the same page in understanding and tackling migration from Central America as a regional issue, not something that one country can handle on its own,” said Christopher Wilson, deputy director of the Mexico Institute at the Wilson Center in Washington. Since much of the money will come through the Overseas Private Investment Corporation (OPIC) and will not cost U.S. taxpayers, it is “the creative solution that was found that makes this much more palatable to the Trump administration,” Wilson said.
